View Full Version : Advice about an extension cable for microphone of my camera
Adriano Moroni April 4th, 2021, 04:43 AM Hello,
I would like to use the microphone from my camera and put an extension cable on it to be able to do interviews, or even other things like singing.
I had seen this cable: https://www.amazon.it/SUCESO-Prolunga-Maschio-Intrecciato-Compatibile/dp/B07K46MDW5/ref=sr_1_3?__mk_it_IT=%C3%85M%C3%85%C5%BD%C3%[/url] 95% C3% 91 & dchild = 1 & keywords = suceso% 2Bcavo% 2Bextension% 2Baudio & qid = 1617519304 & s = electronics & sr = 1-3 & th = 1
I am also attaching a photo of the microphone cable jack.

Can you tell me if the microphone will work without problems?
I would also like to know if I can connect the extension jack on my Asus Zenbook, laptop, to be able to record voice.
THANK YOU for your kind info.
Paul R Johnson April 4th, 2021, 07:32 AM Yes - that cable will do fine - the only snag with doing long cables using 3.5mm connectors is they fall out quite easily - so you need to take the weight off the connectors and use a bit of tape to stop pulls or moves pulling them out.
As for the computer? I'd plug it in and see what happens - usually, there are two possible scenarios - it will work, or it won't. Who knows? Why haven't you tried it?
Adriano Moroni April 4th, 2021, 07:59 AM Thanks a lot for your interesting info.
Out of curiosity: it is constructed with Braided Nylon. Don't you think it's too stiff to put a microphone in?
My mic doesn't work with my Zenbook, maybe the reason is because it has only one connection for headphones and mic (both with same connection).
Thank you again.
Paul R Johnson April 4th, 2021, 08:16 AM The stiffness is a different issue - conventional mic cable is larger and softer. 3.5mm cables are usually used fort headphone extensions, to be honest.
There is a warning that my very poor Italian makes me think about? It says it is NOT suitable for microphones. However this does say it is OK to connect up to speakers and other audio equipment - so I am GUESSING the cable is screened. If it is just three onscreen conductors then it will probably hum like the devil. However, for the price it is worth trying as it probably is screened. Not sure why they give the warning. Mic cable is fine for headphones, but unscreened headphones not for microphones - so it's a bit of a gamble to be honest -- BUT -- I think worth the risk. The wording suggests they don't really know much about it!

It likely needs a TRRS (tip-ring-ring-sleeve) 3.5mm plug. A standard headphone plug is TRS (tip-ring-sleeve). On many laptops, and some smart phones, standard HPs are compatible, There are adapters available on Amazon, eBay and elsewhere.. OR.. there may be a setting somewhere.
Adriano Moroni April 4th, 2021, 09:20 AM I don't understand well.
Maybe do you mean ir? www.amazon.it/dp/B07K47JRJ9/?tag=tomsforum-21&linkCode=ogi&th=1
Thanks
John Nantz April 4th, 2021, 10:13 PM The braided sheath 3.5 mm cable option has one advantage and that is flexibility. I got a couple of them for use with a sport cam (Sony X3000) and an external recorder, while the cam was mounted on a gimbal. The cable had to be light-weight and very flexible so it wouldn’t impact movement of the cam on the gimbal.
To achieve a high degree of flexibility, you know that the internal conductors have to be really fine wires, so, given that, the qustion is, how robust is the cable? The concern “will work without problems?”, then just addressing the cable itself and not the end terminals, the answer would be “Yes”, but conditioned based on the quality of the audio and now long it would last.
If high flexibility and low weight is not a priority, or must-have, if it were me, I would spring for a more robust 3.5 mm cable that would likely last longer and provide a cleaner signal. I think the cable itself is delicate, and that is just a personal opinion. For the use I'm putting it to it works very well.

Something like this might do it.

Pete Cofrancesco April 5th, 2021, 12:22 AM The mic might not work because it could require power or need more amplification than a laptop can provide. This is why most people use usb mics or an external mic pre amp when connecting it to a computer.

Do you mean if I buy a USB adapter, then my mic will work fine wirh laptop?

One last piece of advice since you are more experienced than me. But is there any software that you can install in the laptop that can split the headset from microphone, instead of buying that splitter cable? If there wasn't this possibility, I'll buy it tomorrow, but I'm curious to know if it can be done without it.
Thanks again.
Paul R Johnson April 5th, 2021, 08:59 AM No - if your mic has a 3 circuit jack, and the camera is expecting a 3 circuit jack, then apart from the screening which we don't know - electrically it will work. Some computers are designed to use the 4 circuit connectors - so headphone L, headphone R, mic and shared ground. These will either work or not when you plug your mic into a computer socket - probably 50/50 depending on make and age.
A USB mic device usually has the expectation of a XLR balanced microphone being plugged in. This, you do NOT have.
It's the price of a happy meal - so order the cable and try it. All we can do is guess!
Rick Reineke April 5th, 2021, 09:45 AM I recently bought a China made Y-adapter on Ebay for a two dollars. It has a single 3.5mm TRRS plug on one end, and two 3.5mm female jacks on the other, one for a mic, the other for headphones. It worked as it should, If you will using it a lot, better quality adapters can purchased from the usual smartphone suspects.
Adriano Moroni April 5th, 2021, 11:31 AM Now I understand better.
Do you have a pic of that cable please?
Thank you

Adriano Moroni April 7th, 2021, 02:43 PM I have this cable connected to my mic.

I don't know the reason, but this cable doesn't work with my laptop Zenbook.
I'm not an expert and maybe I have to configure something.
I don't know it. I did some tests but it doen't work.

Like I said before most mics that aren't usb won't work plugged into a computer. You need a pre amp interface or you plug the mic into a camera and then import the video to your computer. The most standard way to record interviews is to get a wireless mic system for your camera.
Richard Crowley July 21st, 2021, 08:48 PM This is a complex question that is not simply a matter of what kind of connector or cable.
1) Most of those 3.5mm TRS extension cables are made for headphones/earbuds, NOT for microphones. The reason that is important is that headphones/earbuds use relatively high-level signals that do NOT require shielding. So most of those cables are NOT shielded. But microphones require shielded cables because of their very low signal levels. If you can find a 3.5mm TRS extension cable that claims to be SHIELDED, then that is the one to use for your microphone. (British English "screened" = shielded)
2) Microphones with 3.5mm TRS plugs come in several varieties and are wired differently. So, they will not just work properly with any random 3.5mm TRS destination gear.
a) A microphone made to use with a computer has the mic connected to the Tip, and the power for the microphone connected to the Ring. And the Shield/screen/ground is connected to the Sleeve. For more technical details, see: https://www.hobby-hour.com/electronics/computer_microphone.php
b) The microphone input on virtually all consumer camcorders is wired for a stereo microphone with the Left mic on the Tip, and the Right microphone on the Ring.
So, if you plug "computer mic" into a typical camcorder, you will likely get sound recorded only on the Left channel.
So, you can confirm how your (unidentified) microphone works with your (unidentified) camera by simply plugging it in and trying it. It probably won't damage anything to do this test. If you get sound only on the Left channel of the recorded video, then you are probably using a mic designed for a computer.
Then, after you are satisfied that the microphone works with your camcorder directly plugged in, you can try a mystery cable like that "SUCESO". It does not mention anywhere that it is shielded, and long experience with such products suggests that it is NOT shielded. If it were shielded, then the marketing wanks would certainly tout it as a major feature, even if it is not important for headphones/earbuds.
Adriano Moroni July 22nd, 2021, 12:19 PM Interesting reply. Please, could you suggest a preciseSuceso cable for a mic?
I thank you again.
Paul R Johnson July 22nd, 2021, 02:26 PM There will me ready made ones available in Italy - you just need a 3 circuit (not the 4 in the link) that uses screened cable. Or you find somebody who can solder and get them to make one - it really is not complicated for anyone who can solder and the parts are quite cheap.
Searching for trs 3.5mm screened male female brings back many. Some are screened - some of course don't appear to be. 3 circuit TRS is the vital feature with screened cable - some headphones ones use screened cable - they will be fine too.
Adriano Moroni July 22nd, 2021, 03:01 PM Hey, I have just found them:
Cavo convertitore da TRS a TRRS, adattatore per cuffie da 3,5 mm TRS a TRRS, adattatore audio mobile universale (3,5 mm) per telefoni cellulari, tablet, penne di registrazione, fotocamere DSLR : Amazon.it: Elettronica
OR it
BOYA BY-K6 3,5 mm TRS femmina a Type-C maschio adattatore audio per DJI OSMO POCKET : Amazon.it: Elettronica
In your opinion are they good?
Thank you so much.
Paul R Johnson July 23rd, 2021, 12:59 AM No. The Italian Amazon link doesn’t work but one is an adapter from 4 to 3 you do not want an adapter you want a three circuit screened 3.5mm TRS cable. You have no idea how adaptors are wired.
Just get a cable a male 3.5mm trs to female. We cannot make this any simpler than this. NO adaptors.
Greg Miller July 24th, 2021, 09:49 PM Other people have given you a lot of theory which is mostly correct, but you obviously don't understand electronic theory (if you did, you wouldn't be asking this question). Don't try.
Rick's post #22 is exactly right. If you get an adapter like that, and plug your camera mic into the jack with the mic picture, it should work. If not, then either (a.) your computer can not record from a microphone, (b.) your camera microphone is *not* standard, or (c.) your computer's sound settings are incorrect {I can't help you, I know nothing about Zenbooks; read the manual}.
With a normal camera mic and proper computer setup, the following should be everything you need, in five simple steps. These simple steps should require *no* technical comprehension.
1.) Look at the your mic plug. It has three metal sections (separated by two plastic insulators). Three-section plug is called "TRS" (three metal sections, so the name has three letters).
2.) Look at the plug on the adapter photo (sent by Rick). It has four metal sections (separated by three plastic insulators). Four-section plug is called "TRRS" (four metal sections :: four letters).
3.) Since your mic has a three-section TRS plug, you need an extension cable with three-section TRS plug, **AND** it specifically says it will work with a microphone. That should work for you.
But if it does not specifically say "microphone" then it might produce a lot of hum and noise.
So you must get a three-section TRS extension cable that does say "microphone."
4.) If your computer has only a single jack for mic and headphone, it almost certainly uses a four-section TRRS connector. It WILL NOT work directly with your camera mic. You need an adapter cable like the picture posted by Rick.
In that case, plug your mic into a three-section TRS extension. Plug the TRS extension into the adapter cable, use the jack with a picture of a mic on it. Plug the adapter cable's four-section plug into your laptop.
5.) I am assumting that your camera mic is wired like almost all of them. There is a small chance it is different. If it is different, then (4a.) will not work and you are out of luck using this mic with this computer.
6.) That's everything you need to know. The technical aspects would take a while to explain, which might confuse you. You don't need to know the technical details. The above (1.) through (5.) are everything you need.
I can't make it any simpler than that. If you are still confused, find an audio dealer you trust, explain what you want to do. Amazon has no technical knowledge whatsoever. They are a bulk seller of everything from salad dressing to suppositories ... they know NOTHING about electronics. Go to a real electronics dealer.
